Fenderwasher-Steel/Rubber-1" Od X 5/16"Id

This steel and rubber bonded fender washer is designed for general fastening applications across McNeilus, Terex, and Con-Tech concrete mixers. Measuring 1 inch in outer diameter with a 5/16-inch inner diameter, it combines the load-distributing strength of a steel fender washer with the leak-preventing properties of a compressible rubber face. When tightened, the rubber layer forms a watertight seal against the mounting surface, making it ideal for securing water tanks, fenders, chute components, and body panels exposed to the elements. It also acts as a vibration dampener, preventing fasteners from loosening during heavy-duty transit and mixing operations.

Key Features

• 1-inch outer diameter provides a large bearing surface to prevent fastener pull-through on thin sheet metal or plastic components
• 5/16-inch inner diameter fits standard 5/16-inch bolts, screws, and studs
• Bonded rubber face compresses during installation to create a watertight, weather-resistant seal
• Steel backing ensures structural rigidity and even load distribution across the mounting surface
• Dampens equipment vibration to prevent fastener loosening in high-vibration mixer environments
